Abstract
In this work the cation effect of ion-exchanged y type Zeolite catalyst in the case of cracking and or isomerization reactions of n-pentane were investigated.
Pure n-pentane was converted into various lower hydrocarbons under the conditions of below 2 atm, and 400 ℃ to 600 ℃ through isomerization and cracking reactions.
According to a conventional method, the order of catalytic reactivity of the ion-exchanged catalysts for both reactions were confirmed as following ;
ⅰ） Iomerization reactions, Cr++3-y>Mg++-y, Ca++-y>Fe++-y, Mn++-y>Cd++-y, Cu++-y, Zn++-y>Al+3, H+-y, Mg++-y, Co++-y
ⅱ） Cracking, reactions Ni++-y, Cd++-y>Ca++-y, Cr+3-y, Zn++-y, Mn++-y>Fe++-y Cu++-y, Co++y, Mg++-y, H+-y, Al+3-y, Hg++-y
